What is the correct point of Fausta camshaft?

The following steps are required to calibrate the ignition point of the inlet/outlet injection of the fortress camshaft: 1. Step 1 marking: belt connection, camshaft gear, crankshaft gear marking, cylinder head and cylinder marking. For chain connection, it is necessary to use three chain lobes with the same color, corresponding to different quasi-camshaft and crankshaft gears respectively. For a single camshaft, two points need to be centered. 2. The camshaft is not equipped with chain belt, but is treated with centering wheel. The gear type marked on the surface indicates the camshaft crankshaft. It is necessary to swing the crankshaft and camshaft to the top dead center position of cylinder 1. The marks on the timing sprocket are aligned with the cast inverted triangle on the cylinder block, and the locating pins of the two camshaft sprockets are facing upwards. There is an "I" on the intake camshaft sprocket and an "E" on the exhaust camshaft sprocket. 3. Check the three colored links on the chain, align them with the timing marks "○" on the three sprockets respectively, and then install the chain tensioner. Note: After installation, please remove the spark plug, rotate the shaft manually, then turn the left and right disks for half a turn, and then return to the original position to check whether the timing is correct. You can turn the plate a little, and finally turn it twice to check whether the valve is pushed. 4. The first task of aligning the Duff camshaft is to remove the valve cover and shake the crankshaft so that the depressions of the two camshafts are the same as those of the previous year (the angle of the camshafts when removing the cylinder head bolts). After that, special tools need to be inserted into the rear ends of the camshafts (when shaking) to fix the two camshafts. Remove the bolt on the special bolt hole for fixing the crankshaft on the steel body and the bolt at the lower right of the throttle valve, and insert it as a special tool (shake the crankshaft at the same time until the crankshaft cannot shake up and down) to fix the crankshaft angle; At this time, the time is right.
